Depends on if they used cryptographic signatures. Those would be impossible to spoof because any change in the client would change the hash completely.
I couldn't have been more eloquent myself.
If you don't mind paying, Protonmail. I pay €12 per month for mail and VPN combined however it is cheaper if you only want the email option. I haven't used Gmail in about three years now.
Degoogling is a long and difficult process. I highly suggest you start with small steps. For example, you could start using Invidious to watch Youtube videos. It is definitely not without bugs and you will run into issues. Change your search engine to Duckduckgo or Brave or whatever else you prefer. For general searches, these are good enough. Unfortunately, for addresses and navigation, Google Maps doesn't have a good enough competitor that I know of. I urge you to make Firefox your daily driver if you are still using Chromium-based ones. I have Brave browser as an alternative for sites like banking or to access Maps or Google search. Start an alternate Protonmail account while still using Gmail. Be warned though that the free tier has 500MB, the paid tier 500GB.
If you want to go full hardcore, look into Graphene or CalyxOS as a replacement for your Android. I specifically bought myself a Pixel phone so I can get a degoogled OS for my primary phone. I still have a secondary phone running Android for banking and paying which I turn off when I do not use it. Look into Shelter to freeze apps. For example, Uber doesn't need to know your whereabouts when you are not specifically looking for a cab.
But please, please, DO NOT start doing everything all at once or you will get overwhelmed. I now almost fully use open source stuff, and I pay and donate for services. I think this is the only way to show support for the projects you love and to have a voice against big tech/ad tech.
All hail the hypnotoad! @_@
Europa Universalis 4. Actually most Paradox games.
Even if there is nothing wrong with Meta trying to federate with the Fediverse, I do not want them here.
Honestly, at this point I am quite jaded and sick of the shenanigans of big tech. Repeatedly they have violated the trust of their users. Unless they show active change in the way they conduct their operations for the benefit of the end user and not advertising agencies, I would prefer to not have them in my life if I can help it.
EDIT:
I might have misread the intention of your post. If you are asking about the fallout of Meta federating, there is a possibility that they attract too many users to their platform. This is my personal anecdote. I wanted to get rid of all products owned by Facebook to the point where I told my contacts that I am switching to Signal and will be uninstalling Whatsapp. I even reasoned with them that I wanted to choose not to use Whatsapp, and that I still wanted to communicate with them, albeit on Signal. I even emphasised that I wasn't asking them to uninstall Whatsapp. Ultimately, only about a third of my contacts joined Signal.
Everyone says there is a choice in not using Whatsapp, but is it really a choice when there is no one to talk to on Signal? That is my worry that something similar would happen with Threads.
In fact, forget the Reddit.
Not much, what's up with you, dog?
You want upvote, you get upvote. Now, would you like updog?
The Witcher 3. Sometimes there were no good choices to make and one had to choose the better of two bad outcomes. Sometimes the obvious good choice led to bad things happening to a village. That game was a rollercoaster of emotions.
I also second This War of Mine.
I have a similar setup and decided to install it on my degoogled phone because I definitely wanted to use a VPN to connect to Whatsapp and my other phone is an older Android without the global VPN option.
I have it completely isolated from my main account by using Shelter from F-droid, installing Aurora store in that sandbox and then installing Whatsapp from Aurora into the work profile created by Shelter.
This way, my main contacts and media are not accessed by Whatsapp. It does its own separate thing and I have no other apps interacting with it.
